Objective: To investigate the efficacy and safety of a treatment regimen based on daratumumab in patients with high-risk relapsed refractory multiple myeloma(MM) with mSMART 3.0 score.
Methods: Clinical data were collected from 16 patients with mSMART3.0 score high-risk relapsed refractory MM treated at the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from May 2020 to May 2023, all of whom received daltezumab-based regimen (regimen drugs including dexamethasone, isazomib, bortezomib, lenalidomide). The efficacy and safety of the treatment were retrospectively analyzed.
Results: The median age of 16 patients was 63.5 (47-70) years old, including 10 cases of IgG type, 2 cases of IgA type, and 4 cases of light chain type. The curative efficacy was judged in all 16 patients, with an overall response rate of 93.75% (15/16), including 4 cases of strict complete remission (sCR), 1 case of complete remission (CR), 2 case of very good partial remission (VGPR), partial remission (PR) in 5 cases, and minor remission (MR) in 3 cases. The median follow-up time was 11(2-30) months, and the median progression-free survival and median overall survival were not achieved in 16 patients at the median follow-up period. The hematologic adverse effects of the treatment regimen using daratumumab-based were mainly neutropenia, and the non-hematologic adverse effects were mainly infusion-related adverse reactions and infections.
Conclusion: Daratumumab-based regimen for the treatment of relapsed refractory MM patients with high risk of mSMART3.0 score has better efficacy and safety.

The advent of once-weekly insulin icodec is a promising development in the care of individuals with diabetes. These once-weekly formulations aimed to improve patient adherence and quality of life for patients who find daily injection administration challenging. Insulin icodec has demonstrated comparable glycemic control to conventionally used daily basal insulins, such as insulin glargine and degludec, in the ONWARDS clinical trials.

Deep venous thrombosis (DVT) represents a significant postoperative complication after artificial femoral head replacement, with the incidence increasing proportionally with patient age. This study aimed to evaluate the effect of early postoperative use of intermittent pneumatic compression devices (IPC), followed by the combined use of low molecular weight heparin (LMWH) after 48 hours, for the prevention of postoperative lower limb DVT in elderly patients undergoing hip arthroplasty. The retrospective study included 100 elderly patients who underwent unilateral femoral head replacement.

Purpose: To perform a systematic review and meta-analysis of the outcomes of Anaconda fenestrated endograft for the treatment of complex abdominal aortic aneurysms (cAAA).
Material And Methods: A systematic search of all the literature reported until May 2024 was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The pooled 30-day mortality rate, technical success rate, reintervention rate as well as bridging stent occlusion rate, and corresponding 95% confidence intervals (CIs) were estimated using fixed or random effect methods.
